- enable pthreads build
- switch gp binary to static link libpari; this offsets the slowdown due
to pthreads
- use -flto and -fno-semantic-interposition which improve speed a little
bit more
- ship the static library, so external programs can static link
- change of maintainer agreed by sgn
I had to add a minimal patch to the makefile, so that the build step
builds and the install step installs. I will try to upstream that patch.
